Small-spacecraft Systems and PAyload CEntre (SSPACE) is an interdisciplinary centre involved in the development of satellite systems and mainly driven by students and faculty of IIST. The SSPACE center is involved in realization of payloads, related electronics, small satellites, assembly, integration, testing and ground station to carryout mission operations. SSPACE at the moment is involved in the following missions

• ARIS-2 (Advanced Retarding potential analyser for Ionosphere Studies): This is a PS4 payload for LEO ionosphere studies. After the successful launch of ARIS-1 in April 2019, the data collected was analysed and promising results were found. The ARIS-2 version is getting ready for launch.
• AHAN: This is the first satellite designed and developed by the students of IIST. The mission is expected to be flown on PSLV for carrying out measurements of radiation in LEO. The prototypes of all the subsystems were completed during this period. The satellite is waiting to be integrated and tested.
• PILOT (PslvIn-orbitaLObc and Ttc): This is an offshoot of AHAN where the subsystems developed for AHAN mission will be tested in the PS4 stage prior to the flight. The subsystem designs were completed during this period and are awaiting integration and testing.
• AAReST (Autonomous Assembly of Reconfigurable Space Telescope): This is a collaborative mission with Caltech, USA and University of Surrey, UK. The MirrorSat mass dummy version 2 was delivered to Caltech and successfully completed the integrated vibration test. Furthermore, SSPACE delivered the MirrorSat structure for University of Surrey, UK. This mission is presently suspended.
• RPA for MoM-2 : For understanding the ionosphere of the planet Mars the payload RPA is being developed by SSPACE, IIST. The design of the high sensitive electronics is being developed.
• RPA for Venus: The ionosphere of Venus will be studied by an RPA being developed for the Venus mission.
